本实用新型涉及一种人体使用的电子助听装置,具体地说是一种无线助听器。
目前,一般的助听器由拾音话筒、话筒信号放大电路、音量电位器、功放电路和有线耳机组成。拾音话筒感应到的声音信号,通过话筒信号放大电路进行初放,再经电位器送到功放电路进行功放,再通过连线送到耳机,使耳机振动膜振动、发声、完成助听功能。但这种助听器的拾音器部分和耳机之间有细导线连接,这给使用者的学习、工作、生活及运动造成许多不便。
本实用新型的目的在于提供一种新型的助听器,它将拾音器部分和耳机部分完全分开,中间没有连线,将拾音器部分加装载波、调制及发射电路,使之成为拾音发射器,耳机中装有接收、解调及功放电路,使之成为耳机接收器,以达到两者之间不需连线照样能完成助听的功能。
按本实用新型所提出的无线助听器,它由作为拾音和信号发射的拾音发射器盒和作为信号接收和放大的耳机接收器组成,它们之间采用无线电方法传递信号,因此,拾音发射器盒和耳机接收器为两个不相连的部件,拾音发射器盒由拾音发射器装于盒内组成,它包括下述电路:声音信号经由拾音话筒接收,经放大电路后接音量控制电位器然后进入调制电路,调制电路的载波信号由载波发生电路产生,由电位器输出的音频信号经调制电路调制后进入发射电路,由发射天线发射出去;将上述电路制成电路板,加上电源和开关组成拾音发射器盒;耳机接收器由接收器装于耳塞内组成,其电路为:发射信号经接收电路进入高放电路,再经解调电路解出音频信号至功放电路放大后,进入音频线圈,将其制成电路板,加上电源、开关,装于耳机内,组成耳机接收器。
上述所有电路均是公知电路。
图1为拾音发射器的电路原理图。
图2为拾音发射器的电路原理方框图。
图3为耳机接收器的电路原理图。
图4为耳机接收器的电路原理方框图。
图5为本实用新型的外观图。
图6为拾音发射器的结构图。
图7为耳机接收器的剖面图。
下面结合附图实施例对本实用新型作详细的描述。
本实用新型的拾音发射器为一小型的便携式盒子,边侧有拾音孔(20),带开关K1的音量电位器W1(16),并伸出软发射天线TX1(17),端部为天线挂扣(18),天线内部为柔软型金属,外部包有绝缘织物,盒上部有电池仓盖(19),内装干电池E1(14),盒内装有印刷电路板(15),拾音发射部分的电路元件全部印制于上。拾音发射电原理方框图如下:声音信号被拾音话筒S(21)接收,经放大电路(22)放大后,经音量电位器W1(23)到达调制电路(25),调制电路的载波信号由振荡电路(24)产生,载波信号经过由音量电位器输出的音频信号进行幅度调制后,经发射电路(26)由发射天线发射出去,(27)为电源开关。在图1中,虚线区域(21)由电阻R1、电容C1和话筒S共同完成话筒拾音功能,放大电路(22)由电阻R2、R3、R4、R5,电容C2,三极管BG1、BG2完成话筒信号放大作用,(23)中由音量电位器W1完成音量控制功能,载波发生电路(24)中由电阻R6、R7,电容C3、C4、C5、C6、C7,电感L1和三极管BG3完成载波发生,调制电路(25)中由电阻R8、R9,电容C8和三极管BG4完成调制功能,发射电路(26)中由电阻R10、电容C9、电感L2和发射天线TX1完成发射功能,(27)中E1为电源,即电池(14),电源开关K1附在音量电位器上。
本实用新型的耳机接收器为一小型的无线耳塞,如图7所示,在接收器后盖(4)内的电极簧片(1)中,装有钮扣电池E2(2),(5)为接收器外壳,(6)为印刷电路板,包括了整个耳机接收器的电路元件,(3)为绝缘膜,将电极簧片(1)和印刷电路板(6)隔开,(7)为裸露的接收天线触点,位于耳机头部的边侧,同人体接触后构成感应接收天线TX2,(8)为耳机环形磁铁,(9)为音频线圈SP,(10)为隔离薄膜,(11)为振动片,它们依次装于耳机的头部,为使耳机头部与人耳接触有柔软舒适感,在耳机头部套有软塑料耳套(12),在耳机后部边侧,装有电源开关(13),即图3中的K2。耳机接收原理方框图如下:由于耳机接收器上的天线触头触及人体,当由拾音发射器发出的无线电波通过人体感应经天线触头接收电路(28)送到高频放大电路(29)进行放大,放大后的信号经解调电路(30)检出高频信号,该高频信号经功率放大电路(31)进行放大后送至音频线圈(32),通过电磁感应使振动膜发声,从而达到助听目的。(33)为电源和开关。图3中,虚线区域接收电路(28)中由电容C12、接收天线TX2来接收拾音发射器发出的高频无线电信号,高放电路(29)中由电阻R12、R22,三极管BG12完成高频信号放大功能,解调电路(30)中由二极管D1、电容C22完成解调功能,功放电路(31)中由电阻R32、R42、R52、R62,电容C32、C42和三极管BG22、BG32完成音频信号放大作用,(32)为音频线圈SP,(33)中,C52为滤波电容,E2为钮扣电池,K2为电源开关。
